There was very few occasions when I felt annoyed by travel in STALKER. Most of the time traveling is made fun by enemy respawns, which result in fights that never get old. Besides, I could always use the extra ammo and heals. A bit later in the game I stacked on speed boosting/weight lowering artifacts and could run like a cheetah.
Artifacts are quite important overall. I switched them around all the time as needed for the task at hand. There's an artifact for just about everything in the game... Health, armor, electricity, weight/speed, psi attacks, etc. Since they tend to respawn, and even randomize, you can come back to areas several times, and get several artifacts. Somehow that didn't feel like cheating in this game. It usually does, but this time it didn't!
A little advice for you... If you don't like the game, don't "try" to like it. You are wasting your time. Go out and get some air. In my experience every time I forced myself to play through a game I didn't like, I ended up wasting my time.
Feel free not to read the rest, cause I feel like ranting a bit.
Anyway here goes...
It doesn't matter how many people say a game is good. Why is it that some think that if others say something is good, then it must be good for them? It can be, but that doesn't mean that it is, and if you feel it's not for you, don't try to change that... Everyone said Baldur's Gate was good, but I found it boring and lacking in action and interesting story. Why in the hell should I be restricted when choosing character class? Why cant I create EVERY character in my party and instead be forced to "hunt" for party members? Because some nerd said so? I loved Icewind Dale because I could make my own party members, and I loved Planescape: Torment because it's story was so unique and original, but I hated Baldur's Gate, and I didn't like BG2. I tried these games again and again, and tried to like them, but it was a waste of my time.'
All my friends loved "The Matrix", but I hated it. Everyone was talking about how "deep" the story told in the movie is, and how much lies behind it. I thought it was "nothing special", and I heard it all before in many other other forms. None of the ideas in Matrix were anything new or revolutionary to me. I forced myself to watch Matrix again, and I hated it again... I saw Matrix 2 and 3, and all of it sucked. In fact I laughed, because it was so dumb, especially the "Sleeping Beauty" ending. ROFL. I felt like my intelligence was being insulted, and I wanted back the time I wasted on watching this crap...
Everyone said "Dark Knight" was awesome, but I thought it was crap... I am very sorry for Keith Fletcher passing away, he was a good actor, and he played his part well, but the movie still sucked. Anyone who saw Batman: TAS in the early 90's on FOX, might know what I'm talking about, and what I think batman "should be like". Hell, if anything, Batman Forever with Val Kilmer was much better...
On the other hand, there are few RARE occasions, where forcing yourself to try pays off. I remember when I got into EVE Online, I hated many things about it. I hated the extreme complexity, I hated the pirating, the lame missions, the gate jumping, and many other things. But I stuck with it, and it all started making sense. I was able to see past the occasional mediocrity, the grievers and the pirates, and I found my own niche in this wonderful game... (too bad I still had to stop playing though)
For me part of STALKER's appeal was the fact that I am fluent in Russian, and so I could understand all songs, and jokes. I loled every time I heard bandits cursing, and threatening me in Russian. It was hilarious, for me at least... I also saw Andrey Tarkovsky's film, (Stalker), and even though I thought it was too weird for my liking, I think it helped me "understand" the game better. Honestly, STALKER is one of the best games I played.. EVER. It's that good. There's hardly anything remotely like it. But it doesn't mean you have to share my opinion! You are unique in your own way and you like what you like. Remember the old "Apple Jacks" commercial?
